Problème de connexion Wifi
Bonjour,
J'ai installé les mises à jour qu'Ubuntu me proposé il y a là une semaine, et depuis impossible de me connecter au réseau de mon école.
Cependant, chez moi tout va bien.
Lors de ma tentative de connexion, on me demande en boucle mon login et mon mot de passe pour me connecter (c'est une authentification EAP (PEAP)).
Merci d'avance pour votre aide !

Re : Problème de connexion Wifi
Bonjour,
J'ai eu le même problème à un moment, mais ct en filaire. Alors je te demande si c pas un problème de proxy? une authentification? si c le cas (faut voir avec l'administrateur réseau du lycée).
regarde si tu as dans ta variable d'environnement un proxy
$ echo $http_proxy
si il y a un proxy alors
$ export http_proxy=http://username:password@proxyserver.net:port/
par exemple moi ça donnait
export http_proxy=http://toto:XXXXX@176.18.0.8:3128/
pour ftp la variable c ftp_proxy et pour les https c https_proxy (gmail est en https)
ça se trouve c pas ça mais ça peut peut être t'aiguiller
il y a trois manière de faire: la bonne, la mauvaise et la mienne
